My MBP 15'', A1206 model, just got a black screen after it fell asleep, then it will never wake up. I pressed the power button and closed it. Then I tried to restart. The interesting thing is I can hear the boot sound, brightness adjustment sound etc. I think the system is on. But Screen is complete black, I can't see anything.
Questa è una buona domanda?

Apple MacBook Pro "Core 2 Duo" 2.4 15" (SR) Specs

My best guess on this is the Nvidia GPU processor issue. Most of the time this involves scrambled colors on the screen but also no screen. Contact Apple, they will most likely replace your logic board for free, they also pay for all shipping, it takes about four days total. Here's the Apple site on it: http://support.apple.com/kb/TS2377

Make sure everything is detached... Like USB ports and the like. Same thing happened to me and weirdly enough I had to pull out my headphones from the headphone jack and the screen came back!

Can you connect to an external display and check if that works? Also, shine a flashlight on the display and see if you can see anything.

yes ext display will tell us a lot - good thinking rab777hp. Why didn't I think of that? :-(

Rab you are on target for the place to start. Richdave there is no inverter on a MBP of this ERA. This has a LED backlight not a CCFL. They are 2 different animals that provide the same service.

There is no Mac of any kind with the designation of A1206. Please give us the last three letters of your serial number so we can identify your machine. Usually found in the battery compartment. Thanks

Thanks for all your response, I followed your suggestions, here is what I got:
1. Model number is: A1226 and the last 3 letters of my Serial number is YAM.
2. I did connect the external display, then I pressed start button, again I heard the boot sound, but no display. I can hear the sound adjustment beeps, brightness adjustment beeps and the num lock F6 green light. But I still cannot see anything either the main display or external display. However I'm not quite sure if I do right to make external display work.
3. I used a torch light, but I cannot see anything.
4. Another thing I noticed is after I boot the Mac for a while, even though I cannot see anything, I can hear a very long siren when I tried to shut down but long-press the power button. I don't know if this will help.
